Richard,
rtpproxy classic edition had an SDP attribute that could be inserted to
prevent rtpproxy from operating on the SDP if another rtpproxy had
already been engaged upstream. Does RTPEngine have a similar feature?
Yes, if you include the `loop-protect` option.
Thanks! Are there any SDP interoperability concerns with using it?
Not any more than what you would get with rtpproxy doing the same thing :)
The other aspect of this that I am puzzling over is where the packets in
this loop are coming from. The call is long dead, the ports involved are
not in use (per the RTPEngine call list), but I'm still getting:
Aug 08 12:50:00 gw1 rtpengine[18934]: ERR: [[email protected] port
60368]: Too many packets in UDP receive queue (more than 50), aborting loop.
Dropped packets possible
Are these RTP frames that were previously sent at some point during the
call looping?
Hard to say without any further details. What does "long dead" mean
exactly? Seconds, minutes, hours? A deleted call disappears from the
call list immediately, but components of it (ports in particular) may
remain open for a short period of time until all reference counts drop
to zero. That should take only seconds at most though.
